SwissFEL Furka
The SwissFEL Furka Experimental Station
The Furka experimental endstation, located at the soft x-ray Athos beamline of the SwissFEL, is dedicated to the study of quantum materials using time-resolved Resonant Inelastic and Elastic X-ray Scattering (tr-RIXS and tr-REXS) as well as X-Ray Absorption (tr-XAS) spectroscopy. In particular, tr-RIXS opens new scientific opportunities thanks to its unique capability to probe energy and momentum-resolved dynamics of elementary excitations involving different degrees of freedom in solids.
The endstation is in pilot phase, and user operation will start in January 2024.
